Does anyone other than Stage 6 sell an engine hanger designed to accept a rear facing carb?

Ok, I found them there now. I'm yet to encounter a scooter parts site that has a parts search process that is actually intuitive for me.
They all stretch some, I guess it comes with the process of making clearance. I'm investigating the idea of mounting a longcase on a Buddy 50. A slight stretch is gonna happen just with the engine but I'd like to avoid a noticeable aesthetic change. Just want to be able to run big squishy pothole eating tires.

Some of the short case clones used a rear facing carb. The engine hanger had an opening for the intake to pass through. Unlike the stage 6 the mount bolt went straight across. I've seen that hanger used on a long case clone with a stage 6 rear intake and a 28 flat slide. To make it work he used a 45° pvc elbow to get up, over and past the mount bolt. It seemed to work well

I have a clone intake for a rear facing carb but it's really restrictive.
I like the changes PGO made to the Minarelli design regarding the intake. On the stock Buddy engine the intake is positioned towards the back if the engine, behind the hanger, so rear facing is standard on them.
That's why part of my research into the idea of an engine swap involves the rear intake, the Buddy frame isn't spaced such to allow the carb to stick sideways like on most Mina based scooters.
The swap may never happen, just an idea banging around.

FYI:
The stage 6 rear facing mount, is built for the Aerox, style motor. It doesn't fit the Zuma motor with out of the Box, without modification.

The swap may never happen, just an idea banging around. I know what you mean in regards to the stock "clone" rear facing intake being restrictive. My Ningbo GTX is the same way. I ran all of my 72cc bores with the clone intake manifold and rear air box. I used a Polini CP 24 carb because it was able to fit into the rubber coupling but I aslo bought an adapter that mated the carb mouth to the rubber duct on the air box. If you are only planning on using a long case engine, shouldn't you still be able to use the stock engine mount and rear facing intake set up? If anything the shock mounting location might be different on the cases, which could end up interfering with the air box. In that case, you can look into an air box from a 12" wheel Ningbo GTX. It has a longer hose running from the air box to the carb than the air box that came on my 10" wheel GTX. |

28mm Oko, polini short bell mouth, tea strainer mesh filter, CT manifold -forward facing. Its really loud.

28mm Oko, polini short bell mouth, tea strainer mesh filter, CT manifold -forward facing. Its really loud. Dead forward it at an angle? Carb tilted up or square to the head? I thought about running one of mine forwards for various reasons but wound up going rear on it to avoid having to modify the seat support but also worried about heat with it being over the cylinder. |

It's at an angle.
The CT manifold sold here in Hawaii for jogs are forward facing in the sense that they are larger versions of the stock rubber/plastic intake manifolds for the forward mounted air boxes that bolt up right next to the cylinder shroud.
I was brainstorming a way to run the CT manifold with the 28 oko with a forward mounted air box. The shear size of the oko made it difficult to solve the problem of adapting the carb mouth to the air box. That would require at the least a 90° bend.
My idea for my big block was to run the forward set up but cut a hole on the backside of the forward air box and couple it to the discharge opening of the cylinder shroud. Basically, the idea was to use the cooling fan as a blower (somewhat like a supercharger...but no Super, only just charger). The jog90 fan can move some air.
